.To a/ZZ whom t may concern,.- V

Be it known that we, CHARLES A, ANDER- soN and ERIcK A. ERICKSON, citizens ofthe United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Im rovement in Multiple-Feed Lubricators, an of which the following is a s eciication.

simple mechanism for feeding a fluid, such as a lubricant,in desired quantities in repeated succession through any desired numer of conduits.

A further object of our invention is to rovide means whereby ,the amount of conduits: Fig. 4, a plan in partial horlzontal section: Fig. 5 a section on l1ne 2 3 of Fig. 1.

In the drawings, A indicates a suitable reservoir in the lower end of which is formed a cylinder B having o'rts e leading thereinto from the lower end o reservoir A. Mounted in cylinder B is a piston C provided with a port E which, at its lower end,'emerges from the lower end ofthe piston while at its upper end it emerges from the ,cylindrical face of the piston `at a point somewhat above its lower end. 'Leadlng from cylinder B are the eduction ports f, there being as many ports f as there are ports e, and the said ports being arranged alternately, in order'fthat the upper end of the passage E of the piston C may come into successive registry therewith. The outer end of each eduction port f communicates with a sight-glass g through a discharge tube h, and an eduction ipe J leads from the sightlass. Piston C 1s carried b a stem H whic extends upwardly through the reservoir A and, at its u low, as at H', and journale 1n the cover of uid Y. ejected at any time into any particular con-y reservoir A and rovided with a suitable driving wheel N. he inion M is considerably wider than the gear in order that said gear may be given an axial reciprocation andystill remain 1n mesh with the pinion. In order lto produce the desired axial reciprocation of the piston C we provide the portion IPI of said piston with a radially extending arm on the outer end of which is journaled a roller F and said roller rides upon a circular track G provided at proper intervals with cam ortion Z, said cams being preferably of uni orm height and serving to move the pistonl upward, li. e., through its suction strok'es,v during the rotation of the piston. Gears F and M are-inclosed in a suitable casing L and' said casing carries a plurality of ins Z, one for .each cam Z, (and consequent y oneforeach eduction passage f) said pins extending into the path of travel of roller F when saidroller has been moved u wardly' by engagement with the cam Z. he pms Z control the downward or ejecting strokes of the piston C and in order to vary the length of these ejectionk strokes the said pins are preferably threaded through the cover L so as to be ad- 'ustable toward and from track G, said pins eing held in any desired position of axial adjustment by means of suitable check-nuts, or otherwise, as shown.

The operation is as follows: Shaft K is continuously rotated atany desired s eed and piston C is correspondingly rotate b reason of the engagement ofpmion M wit gear F. As the piston is rotated roller F comes into engagement with one of the cams with one o the inlet ports e, thus permitting liquid to ow from the reservoir into` the -lower end of cylinder B. Continued rotation of the piston brings roller F into engagement with one of the pins Z and the piston is thereupon driven axiallyin the opposite direction,

`Z and the piston 1s thereupon raised at a time IOO at a time when the upper end of its passage p n end of cylinder B-out through xp assage E into the corres onding eductionpassage f. The

amount o the ej ecting movement of the piston is determined by the adjustment ofthe upper pin l and may not. be suflicient to move roller F down into engagement with track G, in Which case the piston Will'be supported b the liquid Within the lowerf endof cylinder It will be noticed that any desired inumberof eduction passages may be provided and thatthe amount of liuidejected at any 'ven stroke into any e uction assage may e accurately determined whol y independent of the amount ejected through any other passage.

We claim as our invention:

1. In a pump, the combination, with a cylinder having communicating with the bore thereof, of a piston rotatably and axially reciprocable Withinsaid cylinder and having a passagle formed therein -andcommunicatin With t e cylinder at the end of the piston and adapted to be brought into registry With theinduction ande uctionports successively, a ear carried by said piston, a .second gear mes g therewith to completely rotate the iston, and means for axially reciprocating t e, piston and the gear.
